COMFORTABLE CLIMATE: The ZERN EC-EX06 366/400-2 exchanger maintains a pleasant indoor environment even during dry winter months. By recovering latent heat from water vapor, it effectively prevents mucous membranes from drying out, reduces static electricity, and protects wooden interior furnishings.
Key Features and Benefits of the ZERN EC-EX06 366/400-2
- Unique polymer membrane: The microporous structure allows water vapor to pass through smoothly but reliably blocks bacteria, viruses, molds, and odors.
- High overall efficiency: Maximum energy efficiency thanks to the recovery of both sensible and latent heat while maintaining a healthy humidity level.
- Hygiene standard: Special antibacterial coating of the membrane meets the strictest hygienic requirements for residential and commercial spaces.
- Extra rigid casing: Made of high-strength HPS (high-impact polystyrene) for maximum structural stability and resistance to deformation from air pressure.
- Material safety: Top-quality hot-melt polymer adhesives certified for demanding industrial and medical applications are used in production.
- Frost resistance: The advanced design naturally reduces the risk of condensate freezing, allowing stable and safe operation across a wide range of outdoor temperatures.
Technology and Design by ZERN
The ZERN EC-EX series exchangers utilize an optimized fin geometry to maximize the heat and moisture transfer area while maintaining a minimal pressure drop in the ventilation system:
| Component | Technical Benefit |
|---|---|
| Polymer membrane | Selective permeability only for water molecules; uncompromising impermeability to dirt, gases, and odors. |
| HPS casing | High mechanical strength, precise dimensions of the exchanger body, and a tight fit in the unit slot. |

Frequently Asked Questions
Can the ZERN EC-EX06 366/400-2 exchanger be cleaned?
Yes, the exchanger is fully washable. Perform regular maintenance by gently rinsing it with lukewarm water (up to 30 °C). Never use high-pressure cleaners (pressure washers) or aggressive chemical solvents, as this could cause irreversible damage to the polymer membrane.
Does the exchanger transfer odors between exhaust and supply air?
No. The innovative ZERN polymer membrane operates on the principle of selective filtration, which allows only the water vapor molecules themselves to pass through. Odors, smoke, kitchen or toilet smells, and microorganisms are hermetically blocked by the membrane walls.
